PowerPoint has three main ways to view your presentationnormal view, slide sorter view, and slide show view. Normal view is the view where you will typically create and edit your content. Slide sorter view displays thumbnail pictures of the slides in your presentation. Slide show view displays your slides full-screen and allows you to see your presentation the way your audience will.
To switch between views:
When you first open a presentation, PowerPoint will display your slides so they fit in the Slide pane. The Zoom View allows you to change how your slides are displayed in the Slide pane. Use the Zoom View to magnify your slides to check alignment of text and graphics or to see how your slides will appear when you play your presentation.
To change the Zoom View, click the Zoom button on the standard toolbar. Select a magnification option from the list that appears.
